,'parallelto the shaft 3 and is fixed inthe supports l by set-screWs-or. other suitable devices. This shaft 3a. is

veyer 4 revolubly mou ited therein. The shaft v3" ports in spaced relation, plates 26, forming guides for a brush 27, the-latter extending the entire length "of the magnetic drum, `and normally forced against the outer shell 8 'thereof by springs 28 arranged underneath each end. f f i between the supports and :their respective conveyers, the latter 4' and 4 being driven by pulleys 29 and 30,

',re'spectively, and discharging into chutes 30 and'l arranged at one end of the machine. The magnetic drum is driven from any suitable source of power by a pulley 32 preferably fixedv intermediate the l tact-'wheel 1 1 at its small end.

In the' operation of the machine, both drums are set 'n ets 9, acting to energize them and magnetize the magore or sand containing particles of magnetic metalfare .drum as they come intol contact with the shell 7, ad-

here'thereto and are carried 'toaan elevated position' tially the f ull length of the drur'i and supports' at each 4"innen sl 1e'l1 7A of the drum its entire length directly .'O V er theftriig h For normally forcing this-brush in Contact with' the shell 7,'a spring 17 is positioned under Eccentrically surrounding the drum just described'v in all respects like the shaft 3 and contains a spiral conv In both the Shafts 3 and s suitable opnigs are pro! vided, as best shown in Fig. 1, forming a communication in motion and a current sent through the electrovfmag-v ,100 neticdrum on both its inner and outer shell. Crushed then fed into the small end of both drums. The particles of metal in the materiall fed intofthe magnetic v'vertical 'plane'passing through thev 'drums One of the forms the bottom of a V-s raped trough 25 which sup-V where they are. removed or detached by the brush 16,

said metal particles thereaiter dropping into the trough 14 and passing through the hollow shalt 3 by the action .oi the eonvcyer 4, to the chute 30. The sand and other non-magnetic matter in this drum is gradually worked by gravity in the direction indicated bythe arrows, and discharged at the opposite end of the machine, this gravity discharge being effected by reason of the drums conical form. l

The material fed into the outer drum or elevator 18 is carried by the ribs or corrugations i9 to an eli vated position, where it drops by gravity upon the outer shell 8 oi the magnetic drinn. Such particles of material as are magnetic adhere to the shell,l the remainder again falling to the bottom of the drum. Thisaction is continued until the material non-magnetic in character, is dischagred in the same manneras that fed into the magnetic drums. The particles of the magnetic material adhering to the shell 8 are detached by the brush 27, from which point they drop into the trough 25, thereafter passing through the shaft 3u to the chute 31, through the influence oi the conveyor 4,

As best shown in Figs. 2 and 3, between the inner and outer shells of the magnetic drum and between the several electro-magnets carried therebetween, is larranged non-conducting material as wooden blocks or the like 33. This is, however, not essential and may be dispensed with if desired; also permanent magnets may be substituted for the electro magnets and various immaterial changes may be made .without departing from the spirit of my invention, which is limited by the annexed claims only.
